LUXURY INTERIOR DESIGN SERVICES

The best interiors stop being noticed and start being lived in.

Duet Design creates luxury interiors around how you live, not how a room looks in a photograph. Every project starts with the same question: what does a good day in this home look like for you?

From there, the work is structured, collaborative, and specific to the people who live there. We don’t apply a signature look. Each home gets its own answer.

Why clients turn to Duet Design.

DESIGN THAT STARTS WITH DAILY LIFE

Some firms design a beautiful room first and ask how you’ll use it later. We work the other way. How you cook, host, unwind, and work comes first. The finishes follow.

A PROCESS THAT MAKES HUNDREDS OF DECISIONS FEEL LIKE A FEW

Interior design involves more choices than most people expect: finishes, furnishings, layouts, fixtures. Our process puts those choices in an order that’s easy to follow, so the project keeps moving and no decision lands on you before you’re ready.

A POINT OF VIEW, NOT A FORMULA

Every project is developed as a one-of-one response. We layer materials and furnishings for the people who live there, not from a template, so the home still feels like yours years after installation, long after the trends have moved on.

BUILT TO WORK WITH ARCHITECTURE AND CONSTRUCTION

Interior decisions rarely stay inside the interiors. We work closely with architects and builders so finishes, layouts, and structure develop together. When Duet Forma and Duet Build are part of the project, that coordination starts even earlier.

SPACE PLANNING & LAYOUT

Before finishes, the plan. We work out how rooms connect and how a day moves through the home, so the layout fits the people in it.

What this includes:

Space planning shaped around daily routines
Layouts developed alongside architecture and construction
Flow between rooms and how each space gets used
Early planning that holds up once furnishings and finishes arrive

MATERIALS, FINISHES & FIXTURES

The decisions that give a home its character, chosen for you rather than pulled from a template.

What this includes:

Finish and material selection across every room
Fixture and hardware selection
Material palettes chosen for how they age, not only how they look on day one
Specifications coordinated with the build

FURNISHINGS, ART & LIGHTING

The layer that makes a house feel like the people who live in it.

What this includes:

Furniture selection and sourcing
Lighting design and selection
Art selection and placement
Final styling and installation, from concept through move-in

Devon leads the creative direction of the firm, guiding projects through a design process that balances intuition, structure, and a deep understanding of how clients want to live. Known for her editorial approach to interiors and her ability to translate complex ideas into cohesive environments, she works closely with each client to shape spaces that feel personal, layered, and enduring.

Her leadership has helped establish Duet Design as a studio known for thoughtful collaboration, disciplined process, and interiors that continue to evolve beautifully over time.

Part of the Duet Ecosystem

Duet Design works alongside Duet Forma, Duet Build, and Duet Edit to support homes from early planning through construction and ongoing care.

Each discipline brings its own expertise. All of them share the same standard: clarity in process, integrity in partnership, and homes designed to function beautifully over time.

Client Reviews

Why Colorado Homeowners Trust Duet.

“What really stands out is how thoughtful and well-structured their process is, while still feeling personal and collaborative. They take the time to understand how you live day to day and what matters most, then build the design around that. You can tell there’s real intention behind everything they do.”

“What sets Duet Design apart is their ability to create bespoke interiors that transcend regional design norms and stereotypes. Their work rivals the level of artistry, imagination, and sophistication typically seen on the East and West coasts, yet it’s available here in Colorado. We value their unparalleled dedication to artistry and precision.”

“Duet was able to get inside our heads and interpret our vision for our home, bringing it to life. The design process was made simple because we knew we didn’t have to worry about every decision. They understood our likes, dislikes, and what we wanted, and Devon and her team did all the heavy lifting, easing the burden of decision making on our end.”

“Devon has an incredible eye and is a great leader and mentor for her team of designers. We have had such a collaborative working relationship over the years, and Devon is full of ideas and very professional and productive.”

“People always ask about my house. The elevated experience, the attention to our aesthetic, while bringing new ideas to complement and create a home we are proud of are what sets Duet apart. Thank you for creating a space we love to live in.”

“This design team is focused as they create a unique design specific to the client’s personality and specific needs. This is an extremely talented team that I would recommend to anybody.”

“They’ve built a system that brings clarity to what can otherwise feel overwhelming, especially with a large project. Everything feels organized, well communicated, and tailored to you, without ever feeling rigid.”

“We wouldn’t have opted to do a custom build if it weren’t for Devon. There are simply too many decisions—too many places where things can go wrong—to do a custom-build without a confident vision. Enter Duet: They did a wonderful job of combining [my wife’s and my distinct] styles into a design that we both love for the entire home.”

“They are masters at getting inside their clients’ heads to create designs that truly reflect their tastes and preferences. In a world where a lot of home design looks the same, they make the effort to create one-of-a-kind spaces that honor the folks living in them. They design rooms that not only look amazing but are functional and easy to live in.”

“The rave reviews of their contemporary design work extended beyond myself. I sold my condo within 2 days, likely due to the incredible quality of work I received from Duet ideas, designs and construction implementation. To this day, it remains the coolest condo at the Denver Dry Condominiums.”

“From brainstorming and vision boards to the final reveal, this experience has been fun, exciting, collaborative and, from the client perspective, a breeze. Upon the first steps, the house we moved into immediately felt like a home and we owe all that to the incredible Duet Design Group team.”

“This was our second time using Duet. They really have a way of making spaces look exceptionally unique. My wife and I have pretty different styles, and Duet pulled it off spectacularly.”

“Duet exceeded our expectations (which were already fairly high), on time and on budget. Devon knows what she is doing, as does her entire staff. We were amazed by how well they figured out what we would like and how they pulled together comprehensive designs that we fell in love with when we saw them executed (and we’re pretty picky.)”

“Working with Duet Design Group was an absolute pleasure from start to finish. After selecting images of what I liked and then looking through fabric samples, they were able to nail it regarding my style and colors. Jump forward several months, and I was presented with a home that far exceeded my expectations. I would recommend Duet Design Group to anyone who wants their vision realized!”

“We were on vacation when Duet Design completed the installation [of all design elements to our 1935 Tudor], and we returned to a stunning, beautiful, warm home. We are delighted with the final result, and highly recommend Duet Design for anyone looking to transform a house into a home!”

Duet Design FAQs

What interior design services does Duet Design provide?

Full-service interior design: space planning, finishes, furnishings, lighting, fixtures, art, and coordination with architecture, all led by one team from concept through installation.

Does Duet Design work with outside architects and builders?

Yes. Many of our clients already have an architect or builder in place. We align interior decisions with what’s been designed and what’s being built.

Do you offer interior design on its own?

Yes. Some clients come to us for luxury interior design services alone. Others bring in Duet Forma or Duet Build alongside us. Both are common, and neither is the “right” way to do it.

Does Duet Design have a signature style?

No, and that’s by design. A home shaped around someone else’s signature style rarely reflects the people living in it.

When should I bring Duet Design into my project?

As early as possible. Interior decisions made early prevent headaches later, especially once architecture and construction are underway.

How does Duet Design fit within the Duet ecosystem?

Interior Design is one of four Duet services, alongside Architecture, Construction, and Property & Lifestyle. You’re welcome to engage Duet Design on its own or as part of a fully coordinated project.
